A　modified　YSZ　thermal　barrier　coating　(TBC)　was　prepared　by　simultaneously　depositing　two　components,　NiCrAlY　and　YSZ,　on　nicked-based　superalloy　DZ125　via　atmospheric　plasma　spraying.　In　this　study,　the　sodium　salt　was　deposited　on　substrate　surface　at　the　deposition　rate　of　3　mg/cm(-2).　After　being　heated　at　950　degrees　C　for　50min,　the　specimens　were　cooled　to　ambient　temperature　within　10　min.　The　specimens　were　recoated　after　each　10　cycles.　Subsequently,　the　corrosion　products　were　analyzed　via　X-Ray　diffraction　and　SEM.　The　results　indicated　that　deterioration　of　traditional　YSZ　coating　mainly　resulted　from　the　fluxing　of　thermal　grown　oxides　(TGO).　Conversely,　abnormal　growth　of　TGO　and　enrichment　of　molten　salt　around　segmentation　crack　were　not　observed　in　the　modified　YSZ　thermal　barrier　coating.　Moreover,　the　modified　YSZ-TBC　exhibited　higher　thermal　resistance　than　traditional　YSZ-TBC　in　the　thermal　cycling　testing.
